Abstract:

The aqueous extract of floral parts of Shorea robusta (Dipterocarpaceae) was prepared with cold water maceration. Well diffusion method was employed to determine the effect of antibacterial potential against Gram positive bacteria viz. Staphylococcus aureus and Bacillus subtilis and Gram negative bacteria viz. Klebsiella pneumoniae and Serratia marcescens. Aqueous extract of the plant has showed significant inhibitory activity on different bacterial species tested against penicillin as standard antibacterial agent. Furthermore, the preliminary phytochemical analysis revealed that the aqueous extract found to possess tannins, flavanoids, cardiac glycosides and steroids, which may involve in showing antibacterial activity .
